This morning was another beautiful day in Vacationland to ride my bicycle to work. The photo here I took on my way in this morning. It is a view looking west at the Presumpscot River, down stream of the falls.

For the the the geology nerds. The geology of the area is fairly interesting. The soil are blue-gray marine clays of the Presumpscot Formation. Very typical of coastal Maine. The rocks are WAY more interesting. Silurian to Ordovician Age Hutchins Corner Formation. A flaggy blueish to purplish gray biotite quartz plagioclase granofels with greenish-gray interbeds of calc silicate. Migmatic pegmatite layers commonly interbeded with the host rock, conforming to the bedding. There are also some unmapable pelitic schist layers.
